Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The unit is sonically sealed, which means that water will not get into the light and damage the diodes or circuit board.

Surface-Mount Light

Surface mount light

Surface-mount lights install flat against the surface of the trailer, so a hole does not need to be cut into the trailer for the light. This type of light is installed using a flange or bracket that has mounting holes. And mounting hardware is used to secure the light to the trailer.

P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.

Video Transcript for Optronics LED Reversible Trailer Fender Light Installation

Hi there, trailer owners. Today, we're going to be taking a look at Optronics submersible and reversible LED fender marker light with chrome trim. This marker light is considered reversible because on one side we have our amber light and on the other side we have our red led light Amber for the front and red is for the back. And it's considered reversible because it's the same on both sides and you can easily swap this over to the other side of your trailer and it works fine on both sides. Each of these lights has a single LED. One for the red and one for the amber.

And you can see how small this marker light is. It's considerably smaller than any of your incandescent markers. There's small little peanut bulbs you can get, but with those, you're going to have a light that's going to be this size or larger, and you're only going to get a single function out of it. It's going to produce one color with this one. We are able to have an even smaller size and get both the red and the yellow light.

So having a small form factor in space is good for you or maybe you just don't like the look of big lights, you want something more modern, smaller, and sleek, this is a great option.We've got it installed on our tandem axle trailer here. And I really like the way that it looks. And me personally, when I'm messing around with my trailer, doing some work and stuff, I like to set a lot of things on top of the of the fenders. Maybe I'll sit on them while I'm working on stuff for just a second. And it's nice that I don't have a big bulky light here in the way.

I can kind of have freedom to use the fender as I would use it. Here you can see our old fender. We just got done putting a new fender on this one. And we decided rather than swapping over this old style light here, it's much larger, to give it a much more modern look to it. And you can see how much smaller this is.

This is also an LED light versus the old incandescent light here. And with incandescence, typically the incandescent bulbs are going to be dimmer. So this one, even though it's smaller, it's going to be brighter with a little more presence and it draws less power than the incandescence here.So that means you can potentially run even more lights, or if your trailer is often maybe going off grid, you use solar a lot, by removing incandescent lights and going to LEDs, you can save a lot of energy. And beyond that, LEDs also typically have a lifespan usually about 50 times longer than that of an incandescent bulb. It's a quick and easy installation to get one of these installed. You will have to provide your own mounting hardware so you can get some small button head self-tapping screws. Unless you can reuse your old light's founding hardware if you're just replacing one of those.If you want to follow along with us, it's just two wires to get it connected. Let's go ahead and get that installed now. We'll begin our installation by determining where we're going to place our light. We've decided to put ours right in the center of our fender, which just happens to run right down here along the beam here. And then we are going to put it about three quarter of the way out. So we just measured from six inches out. Now yours is likely going to be different. You can put this anywhere you want on your fender. Doesn't have to go where we we're putting it. So I've gone ahead and made a mark there. And now I'm going to use a three eighths drill bit to drill out a hole. So that's where we're going to pass our wires down through. Now, if you're just replacing an existing light, once you remove the old one, you'll likely already have a hole there that you can pass your wires down through. But since this is a new fender and he has no holes, we're going to have to make our own. So I've already marked out the spot. I'm just going to drill down through it.And now we're just going to put a little flat black paint on it. It's going to match our paint and it's going to protect us from corrosion there. You can also use a clear coat if you don't have matching paint for your fenders. We can now slide our wires down through the hole. You do want to pay attention though. There's a sticker next to your wires, and you can see here that yellow and red. So the yellow is for our amber light reds for the red light. The red needs to face towards the rear of your trailer and the amber towards the front. So we're just going to slide those down through making sure we keep it in the orientation where red is towards the rear. Well, now I'm just going to make sure our light is centered front to back so that way it's going straight down. And then we're going to use small button head self-tapping screws to run it into place. You can get these at your local hardware store. So we're going to leave it just a little bit loose so that way we have a little bit of play in it so we can make sure that it is straight. And then we'll just run in our other self-tapping screw.We're now right underneath the fender here, we've got our wires passed down and then we also have our wiring for our light here. We've got our ground wire and then running from the inside we have our power wire. So we're going to go ahead and strip back. Just starting with the power wire. We're going to do that one first. The wires on our light do come pre-stripped, but I like to strip just a little bit more off of there just to make it a little easier to make my connection. We'll now take a heat shrink butt connector. We're going to slide it onto our power wire. Crimp it down. And then on the other side of our butt connector here, we're just going to bring it on over to our light and attach it to that. We're going to go ahead and twist the wires. You see they kind of frayed. We want to get all those strands in there. We don't want any loose these strands, especially on our power side because those could potentially short out to a ground source. I went ahead and connected the ground wire in the same way that we did our power wire. Now we're just going to use our heat gun to shrink down our butt connectors. If you need any shrink butt connectors, you can get those here at before we go ahead and snap our cover on, I recommend go ahead and testing it out. You can plug it into your truck and turn on your tail lights and we can see it's working properly there. It's just a good idea to test it first in case you need to remove it. Maybe you swapped it and had it the wrong way. Popping these covers off, you do just put a screwdriver under it and pop it up to get it off. But it is made of plastic so you don't want to put dings in it with your screwdriver or anything and potentially causing any damage to it. So now we know it's working, we just set it right down on top and just push it into place. We can then repeat that on the other side if we've got one for over there and you can put as many on as you want. Maybe you got some for the side of your trailer as well. And that completes our look in Optronics submersible and reversible LED trailer fender light with chrome trim.

CS - 05/25/2022


Fast easy transaction for a part I was having trouble finding. Fast ship thank you


It was shipped and received quickly. Is exactly as advertised.


Small. Bright. Will see how plastic pop on cover holds up to boat trailer abuse. Very expensive for what it is.


The side markers are smaller than thought. Hopefully the diodes are powerful enough to be seen otherwise may have to get larger ones. Overall solid products.


All products are in excellent condition, just ordered the lights for spare before trailer manufacture changes design and can get them.


Product arrived promptly and follow-up was excellent.


Perfect match to what I have people really don't carry these lights so glad they did.


Lights were exactly as described and worked perfectly on my fenders. The fenders are diamond-plate and these were small enough to fit well between the tread profile on the fender. My fenders also have wire management inside the fender so these worked very well and provided a nice, clean look as far as how they look after installation.


Like original equipment. Much cheaper than dealer. the model of my trailer didn't come with them. haven't got chance to install yet waiting on wire channel that goes on inside of fender.


Recieved marker lights and had them on that night. mounted on outside of fender .so on comeing traiffic could see the the outside edge of the fenders .nice and bright . trailer is 8x12


It came fast. Hooked it up and is still bright today. One year later I'm Very very happy with this light. Will be ordering more for my other trailers when I change the lights.


Received in a short time. Installed on my trailer and couldn't be happier with the results. Very bright, easily to see, even in bright sunlight. Installation was very easy. I highly recommend this product.


Great to deal with!


Thanks for the follow up making sure I received my order and on top of emails along the way I have not opened any of it yet but I am sure it will be right for I have ordered other stuff and it’s always been correct and very good products. Thank you to your whole staff for always being committed to quality service.


Fast delivery, works and looks great. Excellent service, thanks etrailer!


This LED light is exactly what I was looking for.
It is easy to install , very bright for such a small unit and submersible.


I found a matching light for my Living Quarter fender, it looked so much like the old one I had to look twice. Fast delivery and great quality with a reasonable price I couldn't be happier.


Great quality marker light. Easy to in stall.


Very happy with the service from you people and the product I bought


Great product, No problems,Working great


Very sleek, easy to install, and noticable at night/day.
